In 1972, Ed Muskie, who had run a campaign based on cool and collected competence, enraged by attacks on his wife, famously wept (or didn’t) during a press conference in the snows of New Hampshire, effectively ending his campaign. His emotionalism supposedly indicated that either he wasn’t as controlled and calm as he wanted voters to believe, and he was thus falsely representing himself, or that he was not strong (read masculine) enough to lead the country in the context of the Cold War.

Just a few days ago, all of us old enough to remember 1972 surely remembered Muskie. And most of us—at least those I talked to—thought that Hillary’s tears meant the end of her campaign, already damaged by the loss in Iowa and the paucity of her response to that loss (John Murphy has done a nice job analyzing both).

But according to several people interviewed on various media in the aftermath of the New Hampshire primary, Hillary’s emotionalism seemed to indicate that she “had a soul” (NPR), that she was less programmed than had once been believed, more human.

In both Clinton’s case and in Muskie’s, tears seemed in indicate that what had once been believed about a candidate was wrong—emoting on the campaign trail is understood as more “real” than the carefully scripted messages and managed images. In Muskie’s case, this proved to be disastrous; in Clinton’s, it was fortuitous.

This, of course, is the great joy of politics. All of the planning, the calculating, the careful consideration of a plethora of details may be completely undone by small moments of unplanned spontaneous humanity, moments when candidates reveal themselves in ways they never intended.
